问题 This question already has answers here : ltrim strips more than needed (5 answers) Closed last year . If I do: ltrim('53-34567', '53-'); ltrim('53+34567', '53+'); ltrim('53*34567', '53*'); I get 4567 as the result and not 34567 . What's the explanation for this behavior? 回答1: ltrim('53-34567', '53-'); There is a 5 at the begining of '53-34567' so it is removed. There is a 3 at the begining of '3-34567' so it is removed. There is a - at the begining of '-34567' so it is removed. There is a 3

问题 I'm working with some xml and I'd like to clean it up before I parse it. What i'd like to do specifically, is take the data (example below) and match it on the string " <data> " and then trim everything before it leaving the node in tact. Then I would match on the string " </data> " and truncate everything after it, once again leaving the matched node in tact. Turning this: <dwml> <head> <child></child> </head> <data> <child></child> <child></child> </data> <more></more> </dwml> into this:

C# removing comments from a string

由 ≡放荡痞女 提交于 2019-12-08 05:17:06
问题 I'm using WinForms NET 2.0. I am coding a small function to trim comments from some selected text. What it does is split the selected text by separate lines, and then: If the line contains no comments, it is appended. If the line contains some text followed by comments, it is appended with comments trimmed. If the line starts with a comment, it does not get appended. This is in the if statement. If the line is blank, it does not get appended. This is also in the if statement. Here is my code:
